I'm trying to compile opensmile on Linux CentOS 7 and get the following compilation error:

It might be that the gcc version on CentOS is too old, see https://github.com/audeering/opensmile/issues/18

rbrueckner commented 3 years ago

Thanks! What minimal version of gcc do you suggest?

chausner-audeering commented 3 years ago

Yes, most likely your compiler version is too old. openSMILE requires a C++11-compliant compiler. According to https://en.cppreference.com/w/cpp/compiler_support, gcc versions 5.x and later appear to have basically full support of C++11. In general, I'd recommend to use the latest compiler version available for your operating system, as newer gcc versions also have better code optimization so the binaries built with newer compiler versions tend to run faster.
